Abstract

Apparatus and methods for performing simultaneous time division duplex (TDD) communications are disclosed. A wireless communication device can be configured to establish both a first TDD communication link and a second TDD communication link with a network, such as a telecommunication network. Thereafter, the wireless communication device can send TDD uplink data to the network via the first TDD communication link, and receive TDD downlink data from the network via the second TDD communication link, such that a portion of the TDD uplink data is sent to the network at the same time a portion of the TDD downlink data is received from the network. In this manner, the transmissions of TDD uplink data and the TDD downlink data can occur simultaneously, via multiple communication links. Further, the TDD downlink data can be received in multiple, coordinated data transmissions using Long Term Evolution (LTE) multiple-input and multiple-output (MIMO) antenna diversity.
